spaces in URL

kelyar (Kelyarsky Evgeniy) — Sun, 13 Jan 2008 15:45:12 GMT

This is a workaround to get spaces in URL as pluses not %20 like it is in Rails2.



module ActionController::Routing

  class DynamicSegment

    def interpolation_chunk

      "\#{CGI.escape(#{local_name}.to_s)}"

    end



    def match_extraction(next_capture)

      default_value = default ? default.inspect : nil

      %[

        value = if (m = match[#{next_capture}])

          CGI.unescape(m)

        else

          #{default_value}

        end

        params[:#{key}] = value if value

      ]

    end

  end

end

days in month

kelyar (Kelyarsky Evgeniy) — Tue, 07 Aug 2007 13:10:38 GMT

// returns number of days in specified month



def days_in_month(month)

  (Date.new(Time.now.year,12,31).to_date<<(12-month)).day

end

remove nonprintable characters

kelyar (Kelyarsky Evgeniy) — Mon, 04 Sep 2006 13:08:47 GMT



def printable(str)

  return "" unless str

  eval(str.strip.dump.gsub(/\\[0-9]{3}/,''))

end

Ruby method to get seconds from colon-separated time string

kelyar (Kelyarsky Evgeniy) — Thu, 12 Jan 2006 01:05:37 GMT

// converts colon-separated time to seconds
// "01:02:03" => 3723



def colon_separated_to_i(str)



  time_arr = []

  time_arr = str.split(":").reverse

  sec = 0

  secs = [1, 60, 60*60, 60*60*24]



  time_arr.size.times do {|i|

    sec += secs[i].to_i * time_arr[i].to_i

  end

  sec

end
